Before the concept of guaranteed rookie contracts came into existence in 1995, freshmen were seen as players who usually had a lot of growth in front of them at the college level. The NBA Draft changed forever in that fateful year and now with the "one year out of high school" rule, these first year players are usually seen as the cream of the crop of possible draftees. Since the rule came into place in 2007, we have seen 5 out of 6 #1 picks having just finished their first year of college, with sophomore Blake Griffin being the exception in 2009.
